“…The following treatment, Indoxacarb @ 14.5% SC (1:5.74), was similar to the results of Bajad et al [16]. Spinosad @ 45% SC (1:5.29) was the following course of treatment, which is consistent with Sarkar et al [17] Additionally, Neem oil at 2% showed the lowest benefit-cost ratio (1:4.80), which is similar to the findings from Subbireddy et al [18] and the control plot (1:4.2) (Table 1).…”

A field trail was conducted at Central Research Farm (CRF), Naini, Prayagraj during Kharif from July to November 2021 in Randomized Block Design (RBD) with three replications. Eight treatments were evaluated against Earias vittella i.e., Flubendiamide @480% SC, Indoxacarb @ 14.5% SC, Spinosad @ 45% SC, Chlorantraniliprole 18.5% EC, Neem oil @ 2%, Emamectin benzoate @ 5% SG, Cypermethrin @ 25% EC and untreated Control.Results revealed that, among the different treatments lowest per cent infestation of okra shoot and fruitborer was recorded in Chlorantraniliprole 18.5% EC (8.02%,5.15%). Emamectin benzoate 5% SG (9.26%, 6.75%) was found to be the next best treatment followed by Flubendiamide@480% SC (10.29%, 7.48%), Cypermethrin@25%EC (11.41%,9.24), Indoxacarb @14.5% SC (12.32%,10.00%), Spinosad @ 45% SC (13.13%, 11.53%) whereas Neem oil @ 2% (14.25%,12.70) was found to be least effective against this pest. Among the treatments, Chlorantraniliprole 18.5% EC gave the highest marketing yield and cost benefit ratio (188 q/ha and 1:8.41) followed by Emamectin benzoate 5% SG (176 q/ha and 1:8.41), Flubendiamide @ 480% SC (152q/ha and1:7.18), Cypermethrin @ 25% EC (135q/ha and1:6.22), Indoxacarb @ 14.5% SC (121.2q/ha and1:5.74), Spinosad @ 45% SC (114.6 q/ha and 1:5.29) and Neem oil @ 2% (102.4 q/ha and 1:4.80) as compared to control plot (87.2 q/ha and 1:4.2).

“…Although the plot treated with Spinosad 45 SC attained a higher yield with higher economic benefit, its yield was statistically identical to that of the plot treated with Azadirachtin 1% EC. In case of fruit, 8.03% infestation was noted in the present study, while Subbireddy et al [30] found 11.82% infestation in okra, which was a little higher than our current finding; this might be owing to the use of a lower concentration in the treatment with Azadirachtin. Ukeh and Umoetok [31] reported that a yield of 5.56 t ha −1 in okra was obtained with Azadirachtin 0.15% EC.…”

Evaluation of Biological Approaches for Controlling Shoot and Fruit Borer (Earias vitella F.) of Okra Grown in Peri-Urban Area in Bangladesh

Irrational applications of insecticides on vegetable crops are very common in Bangladesh, resulting in harmful consequences for the environment and human health. Therefore, a study was conducted to evaluate the efficacy of biological and botanical insecticides on okra shoot and fruit borer grown in open fields. Four insecticides were used in this study, namely Bacillus thuringiensis (Bt), Spinosad 45 SC, Abamectin 1.8 EC, and Azadirachtin 1% EC an untreated control. The experiment used a randomized complete block design (RCBD) with three replications. The results showed that the rate of shoot infestation was the lowest in the Spinosad-treated plot (3.80%), and the highest was in the control (20.67%). The lowest fruit infestation (3.56%) was recorded in the treated plot of Spinosad. The rate of reduction of fruit infestation over control was 80.69, 60.14, 56.45, and 55.58% in the plots treated with Spinosad, Bt, Azadirachtin, and Abamectin, respectively. Consequently, the Spinosad-treated plot attained the highest yield (8.65 t ha−1), which was followed by the plots treated with Azadirachtin (6.74 t ha−1), Bt (6.28 t ha−1), and Abamectin (6.12 t ha−1). The highest net return and benefit–cost ratio (BCR) were 542.36 US$ and 2.64, obtained respectively from the Spinosad-treated plot. The second highest BCR (1.70) was obtained from the Azadiratin-treated plot, and the lowest BCR (1.18) was recorded in the Abamectin-treated plot. Therefore, the studied insect management practices could be incorporated to attain higher yields and economic benefits for growing okra in Bangladesh.

“…Dhar and Bhattacharya (2015) [2] evaluated that single application of Imidacloprid 17.8% SL followed by twice applications of Spinosad 45% SC gave maximum reduction in infestation of fruit borer in okra. Subbireddy et al (2018) [15] observed lowest number of larvae and per cent fruit damage on number as well as on weight basis of fruit borer on okra in neem oil 0.3%, azadirachtin 0.15 EC 0.00006% followed by NSKE 5% and garlic bulb extract 3% during kharif and summer season. Senguttuvan and Rajendran (2001) [13] reported that treatment NSE (5%) recorded lower fruit damage to the extent of 11.3% over untreated check (31.3%) due to fruit boring pests in okra.…”

“…Helicoverpa armigera (Hubner) is alone reported to cause damage to the extent of 3.5 to 90 per cent to okra in different parts of the country. In general, the overall damage due to insect pests accounts to 48.97 per cent loss in fruit yield (Subbireddy et al, 2018) [15] . Majorly to manage these pests there is abusive use of broad spectrum chemicals which lead to tribulations of resistance, resurgence of secondary pest, phyto-toxicity, toxicity to beneficial organisms, intoxication of farm personnel and environmental pollution.…”

The field experiment was carried out to investigate effect of some phototropical, mechanical and botanical control measures in comparison with chemical treatment against okra shoot and fruit borers on okra under field condition during kharif, 2019. The minimum shoot infestation due to Earias vittella were reported in Recommended insecticidal spray (I st Spray and III rd Spray with Imidacloprid 17.8% SL, II nd Spray and IV th Spray with Fenvalerate 20% EC) which was at par with non-pesticidal treatment Removal of infested shoots + Light Traps + NSE (5%) + Yellow sticky trap followed by treatment Light traps + NSE (5%) and Removal of infested shoots + Light traps + Yellow sticky trap. While minimum fruit damage on number as well as weight basis due Earias vittella and Helicoverpa armigera were also observed in above order of treatments.
